Modulation / SWR Meter: Measures the percent modulation of the AM signal.
Note that the CAL/SWR/MOD switch must be in the “MOD” position for the
meter to measure and read modulation.
SWR METER: Measures the ratios of standing wave ratio of the antenna system,
which is critical in properly adjusting the length antenna and all related electrical
connections. This meter will indicate if there are any major changes in these critical
areas caused by such things as humidity, vibration, or corrosion, which will cause the
SWR Meter to rise. A rising SWR indicates that a problem exists.
To Calibrate SWR:
a) Set the radio into the AM mode.
b) Switch the CAL/SWR/MOD knob to the SWR position
c) Transmit by pressing the PTT button on the microphone, and adjust the
SWR/CAL, control until the needle reaches the CAL position on the meter.
d) Put the CAL/SWR/MOD knob back to the SWR position, and read the SWR value.
INSTALLATION
LOCATION OF THE RADIO
Prior to beginning operation if the transceiver, a basic installation must be prepared.
Installation of the transceiver itself is a rather simple procedure. In selecting the
location for the unit, two basic factors must be considered:
A. Access to 230V, 50Hz or 13,8V DC power source.
B. The location must be convenient for running the antenna lead in cable if an
outside antenna installation is proposed.
BASE STATION ANTENNA
Since the maximum allowable power output of the transmitter may be limited by the
Regulations or Licence classes, the antenna is the most important factor affecting
transmission distance. Only a properly matched antenna will allow maximum power
transfer from the 50 ohm transmission line to the radiating element.
The recommended method of antenna turning is to use the built in SWR meter to
adjust the antenna turning for maximum reflected power. The radio may be used with
any type of 50 ohm base station antenna.
A ground plane vertical antenna will provide the most uniform horizontal coverage.
This type of antenna is best suited for communication with a mobile unit. For point to
point operation where both stations are fixed, a directional beam will usually increase
communicating range since this beam antenna also allows the receiver to “listen” in
only one direction, thus reducing interfering signals.

OPERATING PROCEDURES TO RECEIVE
1. Turn the radio ON by pressing the POWER switch.
2. Press the “Mode” selection button (labeled “5” on the button) continuously until
you find the mode of operation you desire to operate in (AM, FM, USB, LSB).
3. Adjust the VOLUME control until you reach your desired listening level.
4. Turn the frequency selector knob to the desired operating frequency.
5. Turn the RF GAIN control completely clockwise.
6. Adjust the “CLARIFIER” control to clarify the SSB signals (start from middle
position).
7. Listen to the background noise coming from the radio. Turn the squelch control
slowly until the noise just disappears. (No signal should now be present). Leave
the control at this setting. The SQUELCH is now properly adjusted. The receiver
will remain quiet until a signal is actually received. Do not advance the knob too
far, as some of the weaker signals will not be heard.
OPERATING PRODEDURE TO TRANSMIT
1. Select the desired frequency of transmission.
2. Set the MIC GAIN control fully clockwise.
3. Activate the press to talk switch. The receiver and transmitter are controlled by
the press to talk switch on the microphone. Press the switch and the transmitter is
activated. Release the switch to receiver.
4. Hold the microphone two inches from your mouth, speak in a clear normal voice.
5. The S-TX meter will indicate power output and the modulation meter will indicate
percentage of modulation as you speak into the microphone.
CAUTION: Be sure the antenna is properly connected to the radio before
transmitting. Transmitting without an antenna or a poorly matched antenna could
cause damage to the transmitter.
RESEIVING SSB SIGNALS
There are four types of signals presently used for communications in the Citizen
Band: AM, FM, USB and LSB. When the MODE switch on your unit is placed in the
AM position, only standard double sideband, fully carrier signals will be detected. An
SSB signal may be recognized while in the AM mode to produce an intelligible
output. The USB and LSB modes will detect upper sideband an lower sideband
respectively, and standard AM signals.
10
SSB reception differ from standard AM reception in that SSB receiver does not
require a carrier or opposite sideband to produce an intelligible signal. A single
sideband transmitted signal consists only of the upper or the lower sideband and no
carrier is transmitter. The eliminate of the carrier from the AM signal helps to
eliminate the biggest cause of whistles and tones heard on channels which make
even moderately strong AM signals unreadable. Also, SSB take only half of an AM
mode therefore two SSB conversations will fit into each frequency, expanding the two
time frequency. The reduction in channel space required also helps in the receiver
because only half of the noise and interference can be received with 100% of the
SSB signal.
An SSB signal may be received only when the listening receiver is functioning in the
same mode. In other words, an Upper Sideband Signal (USB) may be made
intelligible only if the receiver is functioning in the USB position.
If a Lower Sideband (LSB) signal is heard when the receiver is in the USB mode, no
amount of turning will make the signal intelligible. The reason for this may be
understood if you consider that when the modulation is applied to the transmitter`s
microphone in the USB mode, the transmitter`s output frequency is increased
whereas in the LSB mode the transmitter’s output frequency is decreased. The result
in listening to the receiver is that when the MODE switch is in the proper position
(either USB or LSB), a true reproduction of single tone of modulation will result, and if
the tone is increased in frequency (such as a low pitched whistle or a high pitched
whistle) you will hear the increase in the output tone of the receiver. If the incorrect
mode is selected, an increase in tone of a whistle applied to the transmitter will cause
a decrease in the resultant tone from the receiver.
Thus when a voice is used in place of a whistle or a tone, in the proper listening
mode the voice will be translated backwards and cannot be made intelligible by the
voice lock control. When listening to an AM transmission, a correct side band is
heard in either mode since both upper and lower sideband are received. Once the
desired SSB mode has been selected, frequency adjustment may be necessary in
order to make the incoming signal intelligible. The CLARIFIER controls allow the
operator to vary the frequency above and below the exact center frequency of the
received signal. If the sound of the incoming signal is too high or too low pitched,
adjust the CLARIFIER control. Consider it as performing the same function as a
Dictaphone speed control. When the speed is set too high, voices will be high
pitched, and if set too low, voices will be low pitched. Also, there is only one correct
speed that will make a particular tape produce the same sound that was recorded. If
the tape is played on a player that rotates in the wrong direction (opposite sideband),
no amount of speed control (Clarifier) will produce an intelligible sound.
An AM signal received while listening in one of the SSB modes will produce a steady
tone (carrier) in addition to the intelligence, unless the SSB receiver is turned to
exactly the same frequency by the Clarifier control. For simplicity it is recommended
the AM modes be used to listen to AM signals.

Stereo headphones can only be connected via adapter Stereo-to-Mono or must be
equipped with a Mono 6.3 mm phones plug. It is not allowed to connect low
impedance headphones ( with 8 Ohms or less), because EU regulations do not allow
any more to use headphones and outputs where a risk of acoustical shocks may
exists.
Programming Modes
For skilled service people we have provided a sub PCB inside of the radio which
allows programming of several special channel configuration modes. Modifications
are only allowed for use in countries where different modes are allowed. While it is
allowed to sell amateur radios with the extended channel system + standard 10 m
VFO mode in Germany (jumper position 2), some other European countries do not
allow this and accept only the 10 m VFO range. In such cases the jumper must be
plugged from position 2 into the position 1 by your distributor before sales. The reset
button must be pressed after reprogramming.
Repair & Service
If any resending for repairs or warranty matters may become necessary for radios sold
